Terminal notes
F0 Line protection fuse,
dimension depends on feed line
F1 Semi-conductor fuse, possibly extra line protection with reduced cross-sec-
tions only (see Accessories, fuses)
F2 Fuse depends on power supply
BUM 64: F3 Circuit protection for power supply fan
Current-operated e.l.c.b. The principles on which the power converter and the motor work lead to
leakage currents to earth, i.e. the drive may be incompatible with current-
operated e.l.c.b. systems.
For configuration, take into account provisional standard EN 50178:1994
Para. 5.2.11.
K1 Mains contactor
(auxiliary contact for controller enable optional, not absolutely necessary)
BUM 62:
L1, L2, L3, PE
Cross-section of mains connection according EN 60204-1:1992
For cable-laying, refer to EMC information.
If UL508C has to be observed: Use 60°C / 75° C copper conductors only
(UL508C, Nov 27, 1996, Tab. 39.2).
Nominal tightening torque of the terminal screws: 4 Nm resp. 35,4 pound-
inches.
BUM 63/64:
1U1, 1V1, 1W1,
Mains connection via commutating reactor
Cross-section of mains connection according EN 60204-1:1992
For cable-laying, refer to EMC information.
If UL508C has to be observed: Use 60°C / 75° C copper conductors only
(UL508C, Nov 27, 1996, Tab. 39.2).
Nominal tightening torque of the terminal screws: 4 Nm resp. 35,4 pound-
inches.
BUM 62:
U, V, W, PE
BUM 63, 64:
1U2, 1V2, 1W2,
Cross-section of motor connection according EN 60204-1:1992
For cable-laying, refer to EMC information.
Screening only necessary, if a spacial separation of the signal cable is not
possible or a noisy communication is expected. In this case the motor con-
nection’s screen has to be connected with low impedance on both sides.
If UL508C has to be observed: Use 60°C / 75° C copper conductors only
(UL508C, Nov 27, 1996, Tab. 39.2).
BUM 62: Nominal tightening torque of the terminal screws: 4 Nm resp. 35,4
pound-inches.
BUM 63, 64: Nominal tightening torque of the terminal screws: 6 Nm resp.
53,1 pound-inches.
ZK+, ZK- DC link of further units if the total power of the input rectifier is not exceeded.
(max. 36 kW, see Technical Data, input rectifier).
Moreover DC link of further units e.g. ballast.
The intermediate circuit carries electrical potential: it is imperative that the
provided cover is used.
If UL508C has to be observed: Nominal tightening torque of the terminal
screws: 4 Nm resp. 35,4 pound-inches.
